Applying Building Information Modelling to Existing Buildings.• This presentation is highlighting the benefits of using the latest Laser Scan Technology in conjunction with Building Information Modelling.• To understand the full advantages of applying Building Information Modelling to existing buildings, this presentation will use the example of this auditorium.• The Following is an example of the information that can be attained from a laser scan, and what this data can be used to achieve.
“Building Information Modelling is digital representation of physical and functionalcharacteristics of a facility creating a shared knowledge resource for information about it forming a reliable basis for decisions during its life cycle, from earliest conception to demolition.” Building Information Modelling, Drawing is Dead – Long Live Modelling Keith Snook, RIBA Director of Research & Technical, http://www.cpic.org.uk/en/current-projects/bim/building-information-modelling.cfm

What is a laser Scanner?• Devices which lead a Laser Beam are called Laser Scanners. There are Laser Scanner heads which can be attached to Coordinate Measuring Machines (CMMs) for the documentation of sites and buildings.A Coordinate Measuring Machine (CMM) captures 3D data from objects to give the position in XYZ, vectors etc. of the object.• A Laser Scanner emits a Laser Beam and then measures the angle and distance of the return laser beam by accurately measuring the time of the return Laser Beam.• Laser Scanning means that surfaces or 3D forms are swept over in a horizontal or grid pattern with a Laser Beam to measure or process these to generate a 3D picture. The Scan Data can be saved to various file formats for manipulation and analysis.
Why use a Laser Scan in Building Information Modelling?• The Laser Scan Information can be accurate to within 0.01mm, and therefore can be used to generate an accurate record of a building.• The information from the scan can be used to generate a Building Information Model of the existing building.• Having an accurate Building Information Model at the commencement of a Project will reduce risk of errors that would otherwise be caused by lack of information in a traditional survey.• Additional information that may be requested from the survey will already be in the scan, and can be extracted to the Building Information Model, e.g. the position of sprinklers, pipe and duct works, etc.
